It depends on the individual, but even with small hands, I felt the whole camera+grip was still too shallow.
Dials felt good and buttons size/placement was kind of typical of MILCs (oly/panny), meaning buttons that are smaller and cramped onto a smaller camera body real estate.
However, all was still 'tolerable' to me, (I have small hands after all)
EVF, no surprises, one of the best out there for now,
Could not determine the lag between refresh and shutter press since I did not have my kid with me (the hardest AF test is to shoot a kid indoors
)
Too bad they don't pair it with a cheaper 35 or 50mm which will be the only lens I will buy from the Sony range.
